OF CHICAGO, ILLINOIS.

W'IRE-SPLICER.

Specification of Letters Patent.

Patented Jan. 7, 1908.

To all whom it may concern:

Be it known that I, Gnonon M. GRAHAM, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wirecation.

This invention relates to ties or couplings for uniting the adjacent ends of wires or rods together, and which is more especially adapted for securing together sections of the wire strands used in the reinforced concrete construction which forms the subject matter of my l\prior application for Letters Patent, Seria 0. 349,684, filed December 27, 1906, and the present improvement has for its object to provide a simple and efficient structural arrangement and combination of parts whereby a very substantial connection is effected in a very ready and convenient manner, all as will hereinafter more fully appear.

In the accompanying drawings: Figure 1, is a vertical section of a tie or coupling embodying the present invention. Fig. 2, is a top view of the same. Fig. 3, is a bottom .view of the same. I

Similar numerals of reference indicate like Referring to the drawings, 1 re resents the body of the tie of a hexagon or ot er suitable form and formed with a central screw-threaded orifice 2, in manner similar to the nut of an ordinary screw bolt; and in the producsize may be economically employed as elements in such manufacture.

3 are du licate holes formed in adjacent and paralle relation in the body 1,. and in a direction transverse to that of the screwthreaded orifice 2, and o ening into the same. It is a material part of t e present invention-- that the diameter of the screwthreaded orifice 2, be much greater than the combined diameter of the holes 3, for reasons hereinafter set forth. 7

The holes 3"are adapted to receive the ends 4 and 5 of the wires to be joined, and to this end the respective wire ends are passed in opposite directions through the respective hoes as shown. It is within the scope of the present invention to merge the two holes into a single oblong orifice adapted to receive the 1 adds to the cost without increasing the chiciency of the device.

6 is a clamping plug formed with a screwthreaded periphery corresponding to and fitting the screw threaded orifice 2. of the tie body; such plug is provided at one end with a non-circular portion or head 7 to afford means for effecting manual rotation of the plug, while at its other end said plug is formed with an obtuse cone. projection 8 of greater diameter than the combined width of the wires to be joined and adapted to enter the space between the wire ends 4 and 5 and, as the clamping plug is screwed into the tie body, force the wire parts within the orifice 2, downward and outward into contact or engagement with the screw threads of the screw threaded orifice 2 to effect a very rigid and substantial locking of the wire ends within the tie body.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is

1. A wire splicer, comprising a nut having a screw threaded orifice of reater diameter than the wire arts to be spliced, and transverse alined l'iolcs intersecting the screw threaded orifice and adapted to receive the wire parts, and a clamping plug'having a screw threaded periphery and a cone projection adapted to enter the space between the wire parts and force the latter forward and outward into contact with the screw threads of the screw threaded orifice.-

2. A wire splicer, comprising a nut having a screw threaded orifice of reater diameter than the wire arts to be sp 'ced, and transverse alined oles intersecting the screw threaded orifice and adapted to receive the wire parts, and a clamping plug having a screw threaded periphery fitting in the screw threaded'orifice and a cone projection of greater diameter than the combined width of the wire parts and adapted to enter the space between the wire parts and force the latter forward and outward into contact with the screw threads of the screw threaded orifice.
